Achieving coexistence between large carnivores and humans in human-dominated landscapes (HDLs) is a key challenge for societies globally. This challenge cannot be adequately met with the current sectoral approaches to HDL governance and an academic community largely dominated by disciplinary sectors. Academia (universities and other research institutions and organizations) should take a more active role in embracing societal challenges around conservation of large carnivores in HDLs by facilitating cross-sectoral cooperation to mainstream coexistence of humans and large carnivores. Drawing on lessons from populated regions of Europe, Asia, and South America with substantial densities of large carnivores, we suggest academia should better embrace the principles and methods of sustainability sciences and create institutional spaces for the implementation of transdisciplinary curricula and projects; reflect on research approaches (i.e., disciplinary, interdisciplinary, or transdisciplinary) they apply and how their outcomes could aid leveraging institutional transformations for mainstreaming; and engage with various institutions and stakeholder groups to create novel institutional structures that can respond to multiple challenges of HDL management and human–large carnivore coexistence. Success in mainstreaming this coexistence in HDL will rest on the ability to think and act cooperatively. Such a conservation achievement, if realized, stands to have far-reaching benefits for people and biodiversity. 相似文献

Waste accumulation is a grave concern and becoming a transboundary challenge for environment. During Covid-19 pandemic, diverse type of waste were collected due to different practices employed in order to fight back the transmission rate of the virus. Covid-19 was proved to be capricious catastrophe of this 20th century and even not completely eradicated from the world. The havoc created by this imperceptible quick witted, pleomorphic deadly virus can't be ignored. Though a number of vaccines have been developed by the scientists but there is a fear of getting this virus again in our life. Medical studies prove that immunity drinks will help to reduce its reoccurrences. Coconut water is widely used among all drinks available globally. Its massive consumption created an incalculable pile of green coconut shells around the different corners of the world. This practice generating enormous problem of space acquisition for the environment. Both the environment and public health will benefit from an evaluation of quantity of coconut waste that is being thrown and its potential to generate value added products. With this context, present article has been planned to study different aspects like, coconut waste generation, its biological properties and environmental hazards associated with its accumulation. Additionally, this review illustrates, green technologies for production of different value added products from coconut waste. 相似文献

环境保护是科学发展观的题中之意,科学发展观关于环境保护的论述,是党的环境保护理论的精髓。学习实践科学发展观活动,是一个哲学内涵非常丰富的课题,是十分难得的研究环境哲学的大好机遇。试点经验显示了环境保护在学习实践科学发展观活动中的重要作用。他们一方面在科学发展中通过转变发展方式,调整经济结构,解决环境难题;一方面坚持环境保护与经济发展并重,在保护环境中求发展,努力实现环境与经济“双赢”。其共性是,注重治本、注重生态、注重政策。深入学习实践科学发展观,关键在实践,要深入一线,深入调研,融人群众的实践,总结来自一线的新鲜经验。要适应新形势,了解新情况,解决新问题。在学习实践科学发展观活动中,不断提高落实科学发展观,在科学发展中,提高解决环境问题的能力,实现环境与发展、环境与经济的“双赢”。 相似文献

This study investigates the inherent optical properties (IOP) of a Brazilian river during a non-natural, anthropogenically
mediated, toxic spill of a wood-pulping factory (the ‘Cataguazes accident’). The results indicated an outstanding transformation
in the river water chromophoric dissolved organic matter (CDOM) pools. For instance, increases in CDOM absorption coefficients,
a
CDOM
(λ), which were averaged at specific spectral intervals, , ranged from 58-fold at the UV-B and UV-A ranges to 95-fold at the PAR range. As a result, the water color expressed as CDOM
absorption at 440 nm, a
CDOM
(440), varied from 4.16 to 365.03 m-1. For S-coefficient, the variations ranged from ∼1.1 to 5.6-fold, respectively, at the 300–650 nm and UV-B range. The variability
of S as a proxy of dissolved chromophores was thus clearly influenced by the spectral range used. Optical proportions were also
investigated through the use of and S ratios at the UV-B, UV-A, and PAR ranges and, in the case of , also at the NIR range. This approach also showed clear variations between the water samples, likely reflecting changes in
the composition of optically active substances in the river system. As a whole, the findings obtained here indicated that
both the quantity and quality of the chromophoric material dissolved in the river water were greatly altered by the toxic
spill. The changes in the optical properties of the river water, although extreme and likely with no parallel in the literature,
were quite rapid as indicated by the optical resilience of the system. Overall, this study indicates that IOP might be thought,
and possibly used, as a metric tool for monitoring the state of waters and aquatic ecosystems. 相似文献

Cultural heritage is being addressed by a number of charters and conventions and it is clear that its consideration within decision-making processes is progressively becoming a real challenge, both for developers and public authorities. Against this background, this paper reviews the environmental assessment framework developed by the European Community, as this should increasingly influence decision making about cultural heritage in an urban setting. The legislative framework for access to environmental information is also reviewed because of its relevance to the decision-making process.The Directives on Environmental Impact Assessment and Strategic Environmental Assessment both require a consideration of cultural heritage in decision making. This requirement can go some way to addressing the paradox in the European Community's position whereby the community wishes to conserve and enhance its own cultural identity whilst, at the same time, cultural heritage is usually defined at a local level. The present paper suggests that, given their flexibility, the two European Community directives on environmental assessment constitute a promising opportunity to address this seeming paradox, but that there is a significant gap between legal obligations and the methodological tools to meet them. 相似文献
